The present invention is directed to crutches, more particularly to a crutch with a leg support that can be unfolded from the crutch.
An individual using crutches may often find him/herself in a location lacking a supportive object such as a table, chair, or cushion for supporting his/her injured leg. The present invention features a crutch device that comprises a leg support for supporting the user's leg when he or she wishes to rest.
Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims.
Referring now to
Pivotally attached to the first end 121 of the shaft 120 is the first end of a leg support bar 210. The leg support bar 210 may be pivotally attached to the shaft 120 via a first hinge. The leg support bar 210 can move between a vertical position (storage position) wherein the leg support bar 210 is positioned above the shaft 120 (in a vertical orientation) and in the crutch frame 110 and a horizontal position wherein the leg support bar 210 is pivoted out of the crutch frame 110 and generally perpendicularly to the shaft 120 (see
As shown in
Pivotally attached to the second end of the leg support bar 210 is a two-legged support component 150. The two-legged support component may be pivotally attached to the leg support bar 210 via a second hinge 162. The two-legged support component 150 can move between a storage position and a usage position. In the usage position, the two-legged support component 150 is pivoted such that it is generally perpendicular to the leg support bar 210. In the storage position, the support component 150 is in line with the leg support bar 210. The support component 150 can be fit into the crutch frame 110. When the support component 150 is pivoted perpendicularly to the leg support bar 210, it can be rested on the ground surface. This positions the leg support bar 210 horizontal to the ground surface and creates a tripod-like support stance. The tripod-like support stance (e.g., three contact points on the ground surface) provides for a stable means of supporting the user's leg.
To use the crutch device 100 of the present invention, a user can pivot the two-legged support component 150 downwardly from the storage position in the crutch frame 110. Next, the user can slide the leg support bar 210 out of the shaft 120. When the first hinge 161 is accessible, the leg support bar 210 can be pivoted downwardly to the horizontal position. The user may wish to tighten the clamp to secure the leg support bar 210. Next, the user can position the two-legged support component 150 such that it is generally perpendicular to the leg support bar 210 and parallel to the shaft 120.
The crutch device 100 may be constructed from a variety of materials. For example, in some embodiments, the crutch device 100 is constructed from a material comprising a metal (e.g., aluminum, steel), wood, plastic, foam, rubber, the like, or a combination thereof.
In some embodiments, the crutch device 100 is constructed such that the leg support bar 210 when in the horizontal position is between about 6 to 12 inches above the ground surface. In some embodiments, the crutch device 100 is constructed such that the leg support bar 210 when in the horizontal position is between about 12 to 18 inches above the ground surface. In some embodiments, the crutch device 100 is constructed such that the leg support bar 210 when in the horizontal position is between about 18 to 24 inches above the ground surface. In some embodiments, the leg support bar 210 is more than about 24 inches above the ground surface.
As used herein, the term “about” refers to plus or minus 10% of the referenced number. For example, an embodiment wherein the leg support bar 210 is about 18 inches above the ground surface includes a leg support bar 210 that is between 16.2 and 19.8 inches above the ground surface.
